“Closing” a blocking queue

Question

I’m using java.util.concurrent.BlockingQueue in a very simple producer-consumer scenario. E.g. this pseudo code depicts the consumer part:

class QueueCo         


        

Answer 1

I have used this system:

ConsumerClass
private boolean queueIsNotEmpty = true;//with setter
...
do {
    ...
    sharedQueue.drainTo(docs);
    ...
} while (queueIsNotEmpty || sharedQueue.isEmpty());

When producer finish, I set on consumerObject, queueIsNotEmpty field to false
